#ifdef DEBUG
#define DBUG(x)	DebugStr x
#else
#define DBUG(x)
#endif

Then write something like:

	DBUG(("fubar"));

This also works with something like printf() (which is how it's usually used).
You can do:

	#define DBUG(x) printf x
	DBUG(("%d fubar %d %s", 1, 2, "ack"));

and have it completely removed when you stop defining DEBUG.  No null
functions, no sed scripts.
